@jacikaas I'm not very up-to-date on anything in these days , but it looks like a preference is missing from the "boards.txt" in Arduino IDE. Which IDE version do ou use? Can you post the "boards.txt" please?

Yes, now I test it with LED+resistor. It's definately broken, becose if I hide PIR sensor, data output always get high. LED light up for a while, then goes down for 2-3s and goes up again. And it repeating all the time, when it is covered (no movement in background).

Tried this setup and its not working very well for me, can be a busted PIR but I don't know.
It seems like it sometimes work, but if I leave the room and then enter it can take long time until the PIR triggers.

If i put a LED and a resistor I do that between GND and signal or where do I place it?
